metallic pinkish, tarnishing to a metallic blue, sooty black when amorphous
Metallic, Earthy
4 - 4½
Specific Gravity:
Crystal System:
Named after J. W. Greig (1895-1977), a mineralogist and physical chemist at Pennsylvania State University, State College, Pennsylvania, USA
Linnaeite Group and Thiospinel Group.

Iron thiospinel occurs always in small crystals to 0.03 mm and as an X-ray amorphous colloidal precipitate from an iron sulfide gel known as the melnikovite of Doss.
Greigite is metastable with respect to pyrite and marcasite.
